Officers went to the Beaver Street Market just before 10 p.m. after a clerk was confronted by a man who demanded cash at knife point.

Police are asking for the public's help in finding the robber, who was described as a white, averaged-built male, approximately 5 feet, 8 inches to 6 feet tall who was wearing a dark-colored hooded sweatshirt, dark winter zippered jacket and blue jeans.

The man left the store through the front door and was able to get away with an undisclosed amount of cash.
